**Dataset formats**

The input and output datasets are in tabular_ format.
The input dataset must have columns with KEGG gene ID and pathways.
The output dataset is described below.
(`Dataset missing?`_)

.. _tabular: ./static/formatHelp.html#tab
.. _Dataset missing?: ./static/formatHelp.html

**What it does**

This tool produces an image of a KEGG pathway, highlighting (in red) the
modules representing genes in the input dataset.  Click here_ for help
with reading the pathway map.

NOTE:  a given gene can
be assigned to multiple modules, and different genes can be assigned to
the same module.
